HANGING-LAMP SUPPORT.

SPECIFICATION forming part of Letters Patent No. 419,575, dated January 14, 1890.

Application filed March 26, 1889t Serial No. 304,822. (No model.)

' To all whom it may concern:

Be it known that I, FRANK F. WARD, a citizen of the-United States, residing at Kalamazoo, county of Kalamazoo, State of Michigan, have invented a new and useful Adjustable Lamp-Support, of which the following is a specification.

The object of this invention is to construct an adjustable support for a hanging lamp for attachment to the upper wall of a room, whereby the lamp may be situated at different places in the room and readily shifted from one place to another by said support.

In the drawings forming a part of this specification, Figure 1 is a side elevation;

Fig. 2, lettered details from Fig. 1, enlarged; Fig. 3, a view looking from a point at the right of Fig. 2, with part in section on line 3 3 in Fig. 2; and Fig. I is a broken plan of an upper wallof a room.

Referring to the lettered parts-of the drawings, A is the upper or overhead wall of a room.

At 0 is a pendent support composed of two swiveled parts 0 X, Figs. 2 and 3, and designed for central attachment to the wall A by means of the screw part X, Figs. 1 and 4. The lower end of the supportC is slotted and provided with a roller 2'.

The bar 13, of any suitable material and any -desired shape in cross-section, is passed through the slot of the support 0 and rests on the roller 2'. Above the bar B a shaft 6 is journaled in the support 0, said shaft having a lever or, as here shown, a lever-wheel D on the back end. A portion of the forward end of the shaft 6 is cut away, leaving a projection e atone side of the axial center of said shaft.

At Z is a loop bearing a roller a, resting on the bar B, and having below said bar a hook a, upon which the lamp L is suspended. In the corners of the room and at the sides it is designed in using the lamp-support to employ hooks a: w, pendent from the wall A overhead. The forward end of the bar B has a hook h, which hooks over one of the hooks to and supports this end of the barB. The hook it has a ring w at the end to catch a hooked rod to operate the support by said rod. (Not here shown.)

The bar B is shown in dotted lines in Fig. 4 in the position it occupies in Fig. 1, and in this position the lamp is situated at one side of the room at or near the center. To change the lamp so as to situate it in the corner of the room, it is necessary to draw the bar B farther forward. To accomplish this it is desirable to relieve the bar 13 from the support of the lamp L. To effect this the loop l,with the lamp, is rolled or moved to the central support 0, and the top of the loop Z receives the projection e. The shaft 6 is then given a halffrevolution by pulling on one of the rings 3 of the chain 1;, which action raises the loop Z, and thus relieves the bar from supporting the lamp. (See Fig. 2.) When in this condition, the bar is carried forward and swung obliquely, owing to the swivel of the support 0, said bar riding on the roller iduring its forward action, and is hooked on the corner hooko: of the room. The shaft 6 is then turned so that the wheel a of loop Z will rest on the bar B, and the lamp is run to the corner of the room and hangs, the same as in Fig. 1, at the end of bar B. On this principle or plan of operation the lamp maybe situated at any desired point in a room. The projection e is really a crank or an eccentric of the shaft 6, and should be properly termed such.

Having thusdescribed my invention, whatj=8o claim, and desire to secure by Letters Paten of the UnitedDStates, is I 1. An adjustable lamp-support comprising a pendent support slotted at the lower end and provided with the roller, a bar adapted to slide in said slot upon said roller at one end and provided with a hook at'the other end, a

supporting-hook, intowhich the hooked end of the sliding bar is caught, and a lamp support or carriage adapted to traverse said sliding bar, substantially as set forth. 7

2. The combinaiion'of the pendent support for attachment to the upper wall of a room, consisting of the two parts swiveled together, a bar having one end held up by said support and forming a sliding attachment therewith, means for supporting the other end of said bar, and a lamp support or carriage adapted to traverse said bar and be supported thereby, substantially as set forth.

port having the slotted end and a roller 1 therein, and the rotatable shaft above said slot having an operating crank or Wheel at one end and an extension at the other end ecccn trically to the axis of said shaft, a sliding bar adapted to pass through the slot of the pendent support and slide on the roller, the forward end of said bar having a hook, a hooked support to support the hooked end of said bar, and a lamp-support consisting of the loop having the roller resting on the sliding bar, substantially as set forth.

In testimony of the foregoing I have hereunto subscribed my name in presence of two witnesses.

FRANK F. VARD.
